VIOLIN CHIN-REST.

Specification of Letters Patent.

Patented Apr. 28, 1914.

Application filed September 13, 1913. Serial No. 789,618.

To all whom it may concern:

Be it known that I, GHARLns J. Ilornvrrorr, a citizen of the United States, and a resident of Baltimore and State of Maryland, have invented an Improvement in Violin Chin-Rests, of which the following is a specification.

My present invention relates to chin and and thus contacting with the violin at these shoulder rests for violins and particularly to that character of device consisting of chin and shoulder plates which are disposed respectively upon the upper and lower surfaces of the violin at its rear edge and held in position by adjustable clamping members. In this type of device, which is now in common use, the clamping members are relatively close together and create a strain at a single point of the violin which is often destructive and in many other cases requires frequent repair. There is a further objection of a serious nature to this type of device in that the outer edges of the chin and shoulder plates are alone support ed the inner edges being free and constant care is required to prevent the inner edges of the plates from being pressed inwardly in contact with the surface of the violin. It is apparent that such a contact destroys in a measure the tone of the instrument and that even the best of care fails at times to prevent this tone destroying contact.

The object of my invention is therefore to provide chin and shoulder plates with extended side shanks adapted to project around one side of the instrument in order to permit of the use of widely spaced clamping members, and in order to effectively prevent the inner portions of the chin and shoulder plates from movement against the surface of the instrument.

In the accompanying drawing which illustrates my invention, Figure 1 is a perspective view of the rear portion of a violin provided with my improvements. Fig. 2 is a detail vertical section taken therethrough substantially on line 2-2 of Fig. 1.

Referring to these figures A represents the chin rest plate and B indicates the shoulder plate, these plates being arranged as is usual upon the upper and lower sur faces of a. violin indicated at C respectively being provided along their outer edges with inner packing strips a and b respectively points only,

The chin and shoulder plates are essentially curved inwardly from the edge of the violin in a degree greater than the curvature of the violin top and base in order that their inner portions may be spaced away from the instrument. The outer or upper surface of the chin rest A is concavcd while the outer or lower surface of the shoulder plate B is curved both concavely and convexly in suitable degree so as to rest comfortably on the shoulder of the performer, The rear outer edges of the chin and shoulder plates A and B are con nected by a single clamping member consisting of right and left hand screw rods {1 and (1, th angular ends of which are embedded or otherwise suitably secured in the plate edges and the threaded ends of which are adjustably connected by a turn buckle sleeve D.

As is usual the chin and shoulder plates are disposed at one side of the rear center of the instrument and in accordance with my invention are provided at one side with extending shanks A and B respectively curved to conform wit-h the contour of the edge of the instrument and adapted to extend for some distance around the edge and to points adjacent the ineurved sides of the violin case. the extremities of these shanks or extensions being also provided upon their inner surfaces with packing strips (0 and b to contact with the surfaces of the instrument and being connected by right and left hand screw rods 6 and c and a turn buckle sleeve E similar in structure to the clamping connection between the chin and shoulder plates A and B. Thus it Will be seen that the clamping members by which the device is clamped upon a violin are widely spaced and the strain on the instrument widely distributed in view thereof. It will further be seen that by virtue of the extending shanks A and B following along the edge of the instrument for a considerable distance, the device may be held in position without tightening the clamping elements to the extent usually necessary. It is to be further noted that the inner edges of the extensions or shanks A and B join the inner edges of the chin and shoulder plates A and B respectively and thus form material supports to prevent the inner portions or the chin and shoulder plates from contact with the instrument.

It will be furtherj noted that by virtue of the packing strips 1 a and Z) and a and Z) upon the inner surfaces of both the chin and shoulder plates and the extremities of their shanks or extensions the major portion of the length of these shanks or extensions are held out contact with the violin surface and thus no wise endanger the tone production the instrument.

inc outer surface curvature of both the in of and base thereof with their inner portions curved away from the violin surfaces, and provided with elongated side GXtOIlSlOIlS said plates being disposed at the rear end of the violin body and having their extensions projecting around one side of the same and curved to emiforin to the curvature thereof said extensions terminating opposite one an other and at points adjacent the waist of the violin body and clamping members connecting the chin and shoulder plates and the extremities of the said extensions.

chin and shoulder plates and their extensions or shanks and the material from which they are made may be varied at some length 1 both to accord with conditions out oi. the

ordinary and the taste of particular per- 1 formers, and the lower suriace of the shoulder plate may be provided With abutter or pad formed of any suitable soft material I for this purpose and indicated in the drawings at 6 I claim 1. The combination vvith a violin, of chin and shoulder plates disposed upon the top Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
